LND386
LOW VOLTAGE AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The LND386 is a power amplifier designed for
use in low voltage consumer applications. The
gain is internally set to 20 to keep external part
count low, but the addition of an external
resistor and capacitor between pins 1 and 8
will increase the gain to any value up to 200.
The inputs are ground referenced while the
output is automatically biased to one half the
supply voltage. The quiescent power drain is
only 24 milliwatts when operating from a 6 volt
supply, making the LND386 ideal for battery
operation.
